Part Number: TLV320DAC32
The TLV320DAC32 is one of our low power stereo DAC that supports headphone outputs. This device has 2 registers pages with around 128 registers that need to be configured in order to use all the functions of the TLV320DAC32. In some cases, the registers configuration may be confusing and it also results in a misuse of the TLV320DAC32. Additionally, it might result in a bad device performance.
Here there are some of the most common configuration scripts for the TLV320DAC32.
These scripts are written in the format w 30 xx yy, where w is an I2C write command, 30 is the I2C device address in hex format, xx is the register address in hex format and yy is the register data in hex format.
Unused I/O Pins Connection Tips.
In some applications, not all the TLV320DAC32 features or pins are completely used. Even in some cases, some pins are not required. One of the most common questions from the users is what to do with these unused pins. In general, for all the audio ADCs, DACs and CODECs, the unused pins follow the next rule:
" All the unused analog inputs (like LINEL or LINER in case of the TLV320DAC32) must be routed to a 0.1uF to 0.47uF to analog ground (AVSS). The rest of unused pins (analog outputs, digital inputs and digital outputs) must be left floated".
Here is an example of the unused analog inputs:
I hope this helps you!!
